. Be lit kllown that JOHN GEMZA andGoN- ,STANTY BALAZX, `both citizensof Poland, ne-

siding at Browmille yand Donora, reepee.- .6. tively, in the countiesoli'Piseataquis and llVashington land States of Maineand `Penn Sylvania,respectively, have inifentedfcertain new and luseful "Improvements inCombination Locks, of which the following is af specilication,

This invention relates generally` to .coinbination locks, being hereshown ,as einblodfied in4 a padlock .comprising` a body member and aInova-ble shackle.

'The Vinvention .has for Ian object `the igor Vision `of a novel type ofcombination loek Whose distin,uishing` `feature is the lacku of anyfixed or set combination, 1and lwhielrinay Vbe `set to any desired'coinloinatim leach Itiine thelock is applied.

`For further comprehension of lthe innention, and of the objectsvandY,,advantages thereof, .reference will be had-to the .lowingdescriptionand zaccoinpanying draw- A ing, .and tothe appended claims-in kwhich the various Y novel features of the l,iniention are moreparticularly `eeft-forth.

gitudinal guide rod 37 fixed at its ends in the casing walls. The topwall of the casing 10 is formed with a longitudinal slot 38 throughwhich project the upper endslof the levers 39 fulcrumed between theirends to the uprights 35, these levers having laterally turned pointerelements 40 yon theirl upper ends that are adapted to register withcertain numbered marks 41 on the top of the casing, these marks having aspacing along the casing corresponding tofthat of the members 27. Atashort distance below its up- "per ends each upright 35 has set slidablyVstrips are formed with shallow vertical notches 47 in which the ends ofthe pins/42 are adapted to engage when the pointers 40 are in registrywith the different marks 41 on the top wall of the casing.

It will be apparent that by moving these uprights 35 longitudinally inthe casing the arms 34 on the shaft 33-may be brought into registry withselected ones of the members 27 so that rotary movement of the saidshaft will cause the arms to engage the selected members and move thesame into or out of neutral position. As here shown the members 27 areprovided on their top sides with cam projections 27 that are engaged bythe ends of the arms 33. To rotate the shaft 34 the latter has a bevelpinion 50 fixed on 4one end that is engaged by a bevel gear 5l on thelower end of a vertical shaft 52 mounted vin the rear end of the casing10, the upper end of this shaft 52 projecting from the casing and havinga knob 53 thereon for purposes of rotation.

To move the uprights along the casing we provide the following means. Apair of vertical shafts 55 and 56 respectively are mounted in the frontand rear ends of the casing, the shaft 55 projecting at its upper endfrom the casing and having thereon a knob 57. These shafts have pulleysor drums 58 fixed thereon, around which a belt 59 is looped, this beltbeing of circular cross section, and passing through suitable aperturesin the uprights 35. Fixed onthis belt is a spherical member 62 that isadapted to engage suitable displaceable devices mounted on the uprights35 to move the latter along the casing 10. These displaceable devicesare here formed by the lower ends of the levers 39, the levers beingaccommodated in vertical `grooves 63 in the uprights 35. At their lowerends these side of the casing and have flat levers or fingers 71projecting upward therefrom.

These fingers 71 are moved into and out of engagement in transverseslots 72 in the members V27, by Vlongitudinal movement of theV bars 70.The longitudinal movement of the bars is effected by the bell cranklevers 73 fulcrumed at the sides of the casing and engaging the bars 70at one end and being connected at opposite ends to the lower ends oflinks74 that are connected at their upper ends to vertically shiftablestraps 75.

The manner of operation of our improved device is as follows z-Assumingthe shackle to be in locking position but with the combination not setand the members 27 also in neutral position. Knob 57 is rotated tocausel the part 62 on the belt 59 to engage the ends of the levers 39 tomove theuprights to selected position with the pointers 40 registeringwith certain of the marks 41. The knob 53 is then rotated, causing theshaft 34 to rock and the arms 43, which have been positioned in registrywith certain of the members 27 to engage these members and move them tolocking position. The knob 57 is then rotated to move the uprights 35back to the rear end of the casing. As will be apparent, in order torelease the shackle it willbe necessary to again set the uprghts 35 tothe position previously occupied in order to bring the arms 34 intoOperativerela'tion to the three members 27 that have been moved tolocking position. To move the shackle 13 to releasing posiytion we mayprovide a cam 75 mounted in the lower end of a shaft 76 and adapted tobear on the crosspiece 12 when the shaft is rotated. The shaft 76 has aknob 77 on its upper end for rotation. 4

Having thus described our invention what we claim as new and desire toprotect by Letters Patent of the United States is as follows 1. In aVcombination lock, a rectangular casing, a movable locking elementhaving fixed thereto a pair of bars extending along the opposite sidesofthe casing, projections spaced along said bars, a series l oftransversely movable plunger members adapted to be selectively moved toengage at their ends tively engage said plunger members to move certainones thereof to operative position, said devices comprising a series ofarms and a shaft on which said arms are slidably mounted.

3. In a combination lock, a rectangular casing, a movable lockingelement having fixed thereto a pair of bars extending along the oppositesides of the casing, projections spaced along said bars7 a series oftransversely movable plunger members adapted to be selectively moved toengage at their ends between said projections to lock the said element,and devices adapted to selectivelyy engage said plunger members to movecertain ones thereof to operative position, said devices comprising` aseries of arms and a shaft on which said arms are slidably mounted, andmeans for moving said arms along said shaft. t

4. In a combination lock, a rectangular casing, a movable lockingelement having lixed thereto a pair of bars extending along the oppositesides of the casing, projections spaced along said bars, a series oftransversely movable plunger members adapted to be selectively moved toengage at their ends between said projections to lock the said element,and devices adapted to selectively engage said plunger membersto movecertain ones thereof to operative position, said devices comprising aseries of arms and a shaft on which said arms are slidably mounted, andmeans for moving said arms along said shaft, comprising uprightsstraddling said arms, guiding means for said uprights, and a beltdisplaceably engaged with said uprights.

5. In a combination lock, a rectangular casing, a movable lockingelement having ixed thereto a pair of bars extending along the oppositesides of the casing, projections spaced along said bars, a series oftransvcrselv movable plunger members adapted to be selectively movedtoengage at their ends between said projections to lock the saidelement, and devices adapted to selectively engage said plungermembersto move certain ones thereof to operative position, said devicescomprising a series of arms and a shaft on which said arms are slidablymounted, and means for moving said armsy along said shaft, comprisinguprights straddling said arms, guiding means for said uprights, leversfulcrumed on said uprights, n

and a belt extending longitudinally of the casing and displaceablyengaged with said levers.

In testimony whereof we have affixed our signatures;
